Working to mitigate beach erosion at Flaxmill Bay

New Zealand - Work is progressing on options to mitigate beach erosion at Flaxmill Bay as part of a wider programme of work to protect our Coromandel coastline. The 2018-2028 Long Term Plan includes $2.6 million over three years to help us implement this through the development of Shoreline Management Plans.

A combination of king tides and an extreme weather event last July last caused significant erosion at Flaxmill Bay and Cooks Beach, and our Council has been discussing appropriate options to address this through a series of community meetings and workshops.

We have a current resource consent application with Waikato Regional Council for a staged rock revetment at Cooks Beach that will transition to a backstop wall and, ultimately, to a soft option (dune plantings) to protect this beach. We are currently finalising the preliminary design drawings for the application, with updates to the beach access and landscaping enhancements.

Once we have these design drawings together we will come back to the community for an update on the project, process and cost to complete this within this financial year (June 2019).

At the same time, we are working on a second resource consent application to build a trial groyne at Flaxmill Bay. The exact location and material for this groyne, which is a low wall extending out from the beach into the sea, is still to be finalised.
